I've restructured the majority of my server for public access. Instead of all the code being able to be accessed directly by the front user, I've moved it out of vision by putting it up several levels, and over a bit.

I had 3 or 4 "mini" sites working off of the same PHP structure, but each had the content copied to its own root folder, when I could have it set up so that they each shared the core frame, and had its own application subdirectory. Which is what is set up now.
